Abstract: A piezoelectric micromachined ultrasonic transducer (PMUT) device includes a substrate having an opening therethrough and a membrane attached to the substrate over the opening. An actuating structure layer on a surface of the membrane includes a piezoelectric layer sandwiched between the membrane and an upper electrode layer. The actuating structure layer is patterned to selectively remove portions of the actuating structure from portions of the membrane to form in a central portion proximate a center of the open cavity and three or more rib portions projecting radially outward from the central portion.

Abstract: Methods and apparatus are described for adapting wake-up signal monitoring to optimize power saving performance. In one embodiment, a UE can be configured to selectively skip WUS monitoring based on a current UE context. In another embodiment, WUS/PDCCH monitoring and/or other UE procedure can be adapted based on a statistic related to the wake-up signals transmitted by the base station to the UE.

Abstract: A method for detecting full-body gestures by a mobile device includes a host mobile device detecting the tracked body of a co-located participant in a multi-party session. When the participant's tracked body provides a full-body gesture, the host's mobile device recognizes that there is a tracked body providing a full-body gesture. The host mobile device iterates through the list of participants in the multi-party session and finds the closest participant mobile device with respect to the screen-space position of the head of the gesturing participant. The host mobile device then obtains the user ID of the closest participant mobile device and broadcasts the recognized full-body gesture event to all co-located participants in the multi-party session, along with the obtained user ID. Each participant's mobile device may then handle the gesture event as appropriate for the multi-party session. For example, a character or costume may be assigned to a gesturing participant.

The optical fiber-based sensing membrane includes, based on a specified geometric pattern of the at least one optical fiber, an optical fiber-based sensing membrane layout. The substrate includes a thickness and a material property that are specified to ascertain, via the at least one optical fiber and based on the optical fiber-based sensing membrane layout, a thermal property or a mechanical property associated with a device, or a radiation level associated with a device environment.

Abstract: A vehicle structure has an energy store receiving space in which an electrochemical energy store is received and is delimited at below by a lower cross member and above by an upper cross member, a longitudinal profile, and a deformation space arranged geometrically between the longitudinal profile and the electrochemical energy store. The electrochemical energy store has an energy store pressure plate on its side facing the longitudinal profile. An extended pressure plate is arranged in the deformation space having a longitudinal profile contact region for contacting the longitudinal profile, an upper pressure plate cross member extending in the direction of the upper cross member, and a lower pressure plate cross member extending in the direction of the lower cross member.

Abstract: The present disclosure relates to methods and systems for providing a touch-based augmented reality (AR) experience. During a capture phase, a first user may grip an object. An intensity of a force applied on the object in the grip and/or a duration of the grip may be recorded. A volumetric representation of the first user holding the object may also be captured. During an experience phase, a second user may touch the object, the object may provide haptic feedback (e.g., a vibration) to the second user at an intensity and a duration corresponding to an intensity of the force applied on the object and a duration of the grip of the object. If a volumetric representation of the first user holding the object is captured, touching the object may also cause a presentation of the first user's volumetric body that holds the object.

Abstract: A cross reality system enables any of multiple devices to efficiently and accurately access previously persisted maps of very large scale environments and render virtual content specified in relation to those maps. The cross reality system may build a persisted map, which may be in canonical form, by merging tracking maps from the multiple devices. A map merge process determines mergibility of a tracking map with a canonical map and merges a tracking map with a canonical map in accordance with mergibility criteria, such as, when a gravity direction of the tracking map aligns with a gravity direction of the canonical map. Refraining from merging maps if the orientation of the tracking map with respect to gravity is not preserved avoids distortions in persisted maps and results in multiple devices, which may use the maps to determine their locations, to present more realistic and immersive experiences for their users.

Abstract: An example augmented reality system includes: obtaining information about an instance of a device; recognizing the instance of the device based on the information; selecting a digital twin for the instance of the device, with the digital twin being unique to the instance of the device; and generating augmented reality content based on the digital twin and an actual graphic of the instance of the device.

Abstract: Techniques of federation of data during query time are disclosed herein. One example technique includes upon receiving an indication of interaction of a file by a user of a tenant, determining whether automatic replication of the file to a user shard corresponding to the user is permitted according to a company policy or a legal requirement, the user shard being in a second geographic region. The example technique can then include when automatic replication of the file is not permitted, storing the file in a tenant shard corresponding to the tenant in a network storage in the first geographic region and instead of replicating the file to the user shard in the second geographic region, creating, in the user shard in the second geographic region, a file reference that is a pointer to the file stored in the tenant shard in the network storage in the first geographic region.

Abstract: A non-transitory computer-readable medium has instructions that, when executed by processing circuitry, are configured to cause the processing circuitry to perform operations that include determining net electric power consumption associated with a first consumer, determining that the net electric power consumption associated with the first consumer is below a threshold level, reducing central electric power distributed from a central electric power source to the first consumer to obtain additional central electric power in response to determining that the net electric power consumption associated with the first consumer is below the threshold level, and distributing the additional central electric power to a second consumer in response to reducing the central electric power distributed to the first consumer.

Abstract: The present disclosure generates a digital twin of the interior of a vehicle to initiate and track maintenance issues. In one aspect, the digital twin is formed using multiple captured images of the interior of the vehicle where multiple components in those images are identified using a machine learning (ML) model. The components identified by the ML model are then mapped to a model (e.g., a 3D model) of the components that lists their location in the vehicle and an identifier (e.g., a part number or serial number). In this manner, the digital twin can identify, using the identifiers, the various components in the images captured by a camera.

Abstract: The ophthalmologic microscope comprises a first component including a base and a stage, a second component including a pivotal arm and a microscope device, and a third component including a pivotal arm and a light source. The various components are mutually pivotal at a hinge. An electronically controlled brake and a position sensor are incorporated into the hinge. The brake controller of the microscope is adapted to interrupt a manual mutual displacement of the components in response to a signal from the position sensor in order to assist the user in properly aligning the components.

Abstract: In a method for measuring the wing edge of a vehicle on a test bed, the test bed has a coordinate system in which the Z-axis is the vertical axis, the X-axis is an axis on the test bed extending in the horizontal plane in the longitudinal direction of a vehicle located on the test bed for testing, and the Y-axis is an axis of the test bed extending perpendicular to the X-axis in the horizontal plane. In determining the position and orientation of the wing edge, a light pattern projected onto a vehicle by an illumination unit is moved and recorded by two imaging units. A subset for evaluation is formed from the 3D point clouds determined stereophotogrammetrically from the recordings.
